Can self-control be improved through daily practice or better technique? In this chapter, I show that the popular idea that self-control is “like a muscle” that can be strengthened through exercise is not supported by recent research. Teaching people “self-control techniques” is no solution either, as it may even widen the gap between those who are good at self-control and those who are not. How about new techniques such as “commitment devices” and “nudging”? Unfortunately, although some nudges seem promising, they cover only a small subset of the situations that call for good self-control. The conclusion of this chapter is that “some people simply have more talent for self-control than others, and therefore some people will have better prospects at achieving health, wealth, and happiness than others. We may have no choice but to accept this reality.”
